What is this box?


Recommended Posts

These were fitted to RAF Rover ambulances & TACRs. They are essentially trickle charged the battery. A very basic charger with a high & low charge rate but has a SCR that can be set to shut it down when the battery has reached the prescribed voltage to prevent gassing of the battery.

 

Internally I found it very crudely constructed, basic principles of soldering a joint were ignored. You should loop a wire through say a solder tag & establish some mechanical linkage & then confirm the electrical joint by soldering. Many of the joints there was no attempt to do this with just straight wire held in a solder-only joint some of which were dry joints. How this got accepted into a defence contract I do not know.

 

Having said that they are extremely rare these days & I sold mine only a few months ago I think for about £50.
